Description

Technical Field

[0001] This utility model relates to the field of auxiliary material bonding machine technology, and in particular to a material feeding mechanism and an auxiliary material bonding machine. Background Technology

[0002] Currently, many components requiring surface protection need to be protected with auxiliary materials such as protective films and protective glass sheets before leaving the factory. To improve processing efficiency, many manufacturers have adopted auxiliary material laminating machines. These machines have an auxiliary material conveying mechanism, a component loading mechanism, and a laminating mechanism. Since materials are generally stored in carriers, during material conveying, the carriers are usually directly transported to the loading position. The laminating mechanism picks up the material from the carrier and transfers it. To reduce costs, when the laminating mechanism has finished picking up the material from the carrier, the auxiliary material conveying mechanism returns the carrier to the loading position. The empty carrier is then moved away manually or by machine, and then the carrier loaded with components is loaded onto the component loading mechanism manually or by machine.

[0003] Since most manufacturers currently use manual handling of the material handling equipment, and the material loading mechanism returns to the equipment in a short time, if the manual handling speed is slow, the equipment may detach from the material loading mechanism and fall to the ground due to inertia, damaging the equipment. This results in high labor intensity for manual workers, who need to be constantly vigilant. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a material feeding mechanism that can shield the material when it returns without affecting the loading of the carrier.

[0005] Another objective of this utility model is to provide an auxiliary material bonding machine having the aforementioned material feeding mechanism.

[0006] A material feeding mechanism includes: a workbench, the workbench is provided with a belt conveyor, the workbench is also provided with an elastic blocking mechanism, the elastic blocking mechanism is located on the rear side of the belt conveyor, the workbench is provided with a groove, the elastic blocking mechanism includes a baffle located in the groove, and an elastic element for pushing the baffle outward is provided between the baffle and the bottom surface of the groove.

[0007] Furthermore, the bottom surface of the groove is connected to several guide posts, the lower end surface of the baffle is provided with guide holes that cooperate with the guide posts, and the elastic element includes a lifting spring, which is sleeved on the guide posts and its two ends abut against the bottom surfaces of the baffle and the groove, respectively.

[0008] Furthermore, the lower end of the guide rod is provided with an external thread and connected to an adjusting nut, and the two ends of the lifting spring abut against the adjusting nut and the baffle respectively.

A drive shaft is connected between the two driving pulleys. One end of the drive shaft extends outward and is connected to a transmission mechanism. A servo motor is connected to the transmission mechanism. The servo motor drives the drive shaft to rotate through the transmission mechanism and drives the two sets of pulley assemblies to move.

[0014] Furthermore, the transmission mechanism includes a synchronous belt drive mechanism.

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 4 As shown.

[0030] Example 1: See Figure 1 , Figure 2A material feeding mechanism 100 includes: a workbench 12, the workbench 12 is provided with a belt conveyor, the workbench 12 is also provided with an elastic blocking mechanism, the elastic blocking mechanism is located on the rear side of the belt conveyor, the workbench 12 is provided with a groove 22, the elastic blocking mechanism includes a baffle 1 located in the groove 22, and an elastic element for pushing the baffle 1 outward is provided between the baffle 1 and the bottom surface of the groove 22.

[0031] The belt conveyor can be an existing technology used to transport the carrier 200. In this embodiment, during operation, the carrier 200 containing parts is manually placed onto the belt conveyor. If the rear end of the carrier 200 is partially exposed, the exposed part will press against the elastic blocking mechanism, pressing the baffle 1 into the groove 22. The baffle 1 does not significantly affect the loading of the carrier 200. After all the parts inside the carrier 200 have been transferred, the belt conveyor will reverse the transport of the carrier 200. At this time, the baffle 1 has been reset under the push of the elastic element and is located at the rear of the belt conveyor. When the carrier 200 moves to the loading position, the belt conveyor pauses, and the rear end of the carrier 200 abuts against the baffle 1, preventing the carrier 200 from moving backward. At this time, the carrier 200 can be replaced manually, thus avoiding the carrier 200 from detaching from the belt conveyor due to inertial speed caused by slow manual replacement.

[0032] Secondly, under normal operation, the upper surface of baffle 1 is lower than that of the vehicle 200. The upper end face is higher than the upper end face of the belt 3 of the belt conveyor. When the carrier 200 is loaded, the carrier 200 can press the baffle 1 downward by 1-3mm.

[0033] See Figure 3 The bottom surface of the groove 22 is connected to a plurality of guide posts 19, and the lower end surface of the baffle 1 is provided with guide holes 18 that cooperate with the guide posts 19. The elastic element includes a lifting spring 20, which is sleeved on the guide posts 19 and its two ends abut against the bottom surfaces of the baffle 1 and the groove 22 respectively.

[0034] In this embodiment, by setting a guide post 19 in the groove 22, the baffle 1 can only move up and down along the guide post 19, and the up and down movement is smooth. Preferably, a limiting spring 23 is connected between the lower end of the baffle 1 and the bottom surface of the groove 22. Specifically, the lower end of the baffle 1 is provided with a hanging hole, the bottom surface of the groove 22 is connected to an annular body, one end of the limiting spring 23 is hooked to the hanging hole, and the other end of the limiting spring 23 is hooked to the annular body. When the baffle 1 is about to detach from the groove 22, the limiting spring 23 is stretched, thus preventing the baffle 1 from detaching. Of course, when disassembling, the baffle 1 can be directly pulled away from the groove 22, and then the limiting spring 23 can be removed.

[0035] See Figure 3The lower end of the guide rod is provided with an external thread and is connected to an adjusting nut 21. The two ends of the lifting spring 20 abut against the adjusting nut 21 and the baffle 1, respectively.

[0036] After setting the adjusting nut 21, the height of the spring and the height of the baffle 1 protruding from the groove 22 can be adjusted, thus avoiding strict dimensional requirements for the baffle 1 and high processing costs. Secondly, baffles 1 of different heights can be used for different fixtures.

[0037] See Figure 1 , Figure 2 The workbench 12 is provided with a plurality of front limit posts 11, which are located on the front side of the belt conveyor.

[0038] To prevent the carrier 200 from continuing to move forward due to inertia after reaching the loading position, this embodiment provides several front limit posts 11 on the workbench 12. When the carrier 200 reaches the loading position, the carrier 200 abuts against the front limit posts 11, preventing it from moving forward.

[0039] See Figure 2 The belt conveyor is provided with several side pillars 8 and side baffles 9 on both sides, and the side baffles 9 are fixedly connected to the side pillars 8.

[0040] When the carrier 200 is conveying, the workbench 12 will vibrate due to the influence of other machines, which will also affect the belt conveyor. In order to prevent the carrier 200 from shifting position during the conveying process, this embodiment is provided with a side baffle 9. In specific implementation, the side of the carrier 200 abuts or is adjacent to the side baffle 9, and the adjacent spacing is very small, such as 1-3mm.

[0041] See Figure 1 , Figure 2 The lower end of the side baffle 9 is bent into an L-shaped bend 10.

[0042] During transport, the carrier 200 is mounted on the belt 3, which moves downwards under pressure. Excessive pressure on the belt 3 can affect the operation of the belt conveyor. Therefore, in this embodiment, the lower end of the side baffle 9 is bent, and the carrier 200 abuts against the bent portion 10 of the baffle during transport. To facilitate this abutment, the carrier 200 has a sloping lower side or its lower bottom surface is inclined, allowing it to gradually contact the bent portion 10 of the side baffle 9 via the sloping front end. This reduces the weight on the belt 3 during transport and minimizes belt sag.

[0043] See Figure 2 The rear end of the side baffle 9 bends outward to form an enlarged portion 7.

[0044] Since the distance between the two side baffles 9 is approximately equal to the longitudinal length of the carrier 200, it is difficult for the carrier 200 to enter the space between the two side baffles 9 during transport. Therefore, in this embodiment, the rear ends of the side baffles 9 are bent outwards to both sides to form enlarged portions 7. The inlet distance between the two side baffles 9 is slightly larger than the longitudinal length of the carrier 200, thereby facilitating the introduction of the carrier 200 between the two side baffles 9 and correcting the position of the carrier 200. The enlarged portions 7 can be inclined or curved.

[0045] See Figure 1 , Figure 2 The belt conveyor includes two sets of pulley assemblies. Each set of pulley assemblies includes a driving pulley 14, a driven pulley 5, and a belt 3. A drive shaft 15 is connected between the two driving pulleys 14. One end of the drive shaft 15 extends outward and is connected to a transmission mechanism 17. A servo motor 16 is connected through the transmission mechanism 17. The servo motor 16 drives the drive shaft 15 to rotate through the transmission mechanism 17 and drives the two sets of pulley assemblies to move.

[0046] In this embodiment, the belt conveyor uses a traditional double pulley assembly. The servo motor 16 drives the transmission shaft 15 to rotate, which in turn drives the two sets of pulley assemblies to move. The belts of the two sets of pulley assemblies move synchronously, thereby driving the carrier 200 to move forward.

[0047] It is understood that: the two ends of the drive shaft 15 are connected to the main fixed block 13 via bearings, allowing the drive shaft 15 to rotate relative to the main fixed block 13, which is fixed to the worktable 12; the driven pulley 5 is connected to the auxiliary fixed block 4 via the fixed shaft 2, which is fixed to the worktable 12. The driven pulley 5 can be connected to the fixed shaft 2 via bearings, and / or the fixed shaft 2 can be connected to the auxiliary fixed block 4 via bearings, allowing the driven pulley 5 to rotate relative to the auxiliary fixed block 4. Furthermore, there can be two fixed shafts 2, each connected to a corresponding driven pulley 5; or there can be one fixed shaft 2, with both ends connected to the driven pulley 5, depending on the configuration. In this embodiment, only one fixed shaft 2 is used.

[0048] See Figure 2 The transmission mechanism 17 includes a synchronous belt transmission mechanism 17.

[0049] To control the conveying accuracy of the belt conveyor, the transmission mechanism 17 adopts a synchronous belt drive mechanism 17. In specific implementation, the rotating shaft of the servo motor 16 is connected to the driving synchronous pulley, and the end of the transmission shaft 15 is connected to the driven synchronous pulley. The driving synchronous pulley and the driven synchronous pulley are connected by a synchronous belt. Of course, the transmission mechanism 17 can also be a gear transmission mechanism 17, etc.

[0050] See Figure 2A support platform 6 is provided below the belt 3. The support platform 6 is arranged in an inverted U-shape, and the upper end of the support platform 6 is located below the belt 3.

[0051] When the conveyor 200 is in use, it needs to be mounted on top of the belt 3, which puts significant stress on the belt 3, causing it to deform and preventing the conveyor 200 from maintaining a constant height during movement. To avoid this, a support platform 6 is provided in this embodiment. The support platform 6 is located below and adjacent to the upper side of the belt 3, with a distance of 1-3 mm between them. In use, when the conveyor 200 is mounted on the belt 3 and the belt 3 abuts against the support platform 6, the shape of the belt 3 remains essentially unchanged. To facilitate fixing the support platform 6, two grooves 22 that mate with the support platform 6 can be provided on the worktable 12, with both sides of the support platform 6 extending into the grooves 22.

[0052] See Figure 2 The lower end of the support platform 6 is bent to form a bent piece 25. The bent piece 25 is provided with several connecting holes and is fixedly connected to the worktable 12 through a connector.

[0053] To facilitate fixing the support platform 6 to the workbench 12, this embodiment uses a bent piece 25 formed by bending the lower end of the support platform 6, and then fixing it to the workbench 12 with connectors such as bolts.

[0054] Example 2: See Figure 4 A material laminating machine includes the aforementioned material feeding mechanism 100. It also includes a laminating mechanism 300 and a material conveying mechanism 400.

[0055] The material loading mechanism 100 transports the carrier 200 and auxiliary materials to a predetermined position. The material conveying mechanism 400 transports the parts to the processing position and then pauses. The bonding mechanism 300 transfers the auxiliary materials to the surface of the parts for bonding and then removes them. The material conveying mechanism 400 then continues conveying. Both the bonding mechanism 300 and the material conveying mechanism 400 can be existing technologies. The bonding mechanism 300 may include a suction cup assembly and an XYZ moving mechanism, and the material conveying mechanism 400 may be a belt conveyor mechanism. The suction cup assembly and the XYZ moving mechanism work together to transfer the materials to the surface of the parts.

[0056] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
